| 摘 要： | 在不同作用时间和pH下,采用动态吸附方法,考察了氧化镁改性沸石对猪场废水的处理效果.结果表明:在不同作用时间和pH下,改性沸石对猪场废水的处理效果均好于天然沸石的;最佳作用时间为4 h,此时改性沸石对氨氮、总磷的去除率分别为88.6%和76.2%;改性沸石去除氨氮的最佳pH值为7,此时去除率为88.7%;改性沸石去除总磷的最佳pH值为9,此时去除率为86.3%.

| Abstract: | At different function times and pH values,the treatment of piggery wastewater by MgO modified zeolite was investigated by applying the dynamic adsorption method.The results show that the treatment efficiency of piggery wastewater by the modified zeolite is better than that by natural zeolite.The removal rates of ammonia nitrogen and total phosphorus are 88.6% and 76.2% respectively at the optimal function time of 4 h.The removal rate of ammonia nitrogen is 88.7% at the optimal pH value of 7,and the removal ... |
